Adam Chalmers a094995730 KCL: Chamfer and fillet now use keyword arguments (#5389)
Previously:
`|> fillet({ radius = 5, tags = [seg01] }, %)`
Now:
`|> fillet(radius = 5, tags = [seg01])`

Also tweaks the formatter for keyword argument calls slightly.

chamfer Cut a straight transitional edge along a tagged path. manual

Cut a straight transitional edge along a tagged path.

Chamfer is similar in function and use to a fillet, except a fillet will blend the transition along an edge, rather than cut a sharp, straight transitional edge.

chamfer(solid: Solid, length: number, tags: [EdgeReference], tag?: TagDeclarator) -> Solid

Arguments

Name Type Description Required
solid Solid The solid whose edges should be chamfered Yes
length number The length of the chamfer Yes
tags [EdgeReference] The paths you want to chamfer Yes
tag TagDeclarator Create a new tag which refers to this chamfer No

Returns

Solid - A solid is a collection of extrude surfaces.

Examples

// Chamfer a mounting plate.
width = 20
length = 10
thickness = 1
chamferLength = 2

mountingPlateSketch = startSketchOn("XY")
  |> startProfileAt([-width / 2, -length / 2], %)
  |> line(endAbsolute = [width / 2, -length / 2], tag = $edge1)
  |> line(endAbsolute = [width / 2, length / 2], tag = $edge2)
  |> line(endAbsolute = [-width / 2, length / 2], tag = $edge3)
  |> close(tag = $edge4)

mountingPlate = extrude(mountingPlateSketch, length = thickness)
  |> chamfer(
       length = chamferLength,
       tags = [
         getNextAdjacentEdge(edge1),
         getNextAdjacentEdge(edge2),
         getNextAdjacentEdge(edge3),
         getNextAdjacentEdge(edge4)
       ],
     )

  |> extrude(length = 20)
  // We tag the chamfer to reference it later.
  |> chamfer(length = 10, tags = [getOppositeEdge(line1)], tag = $chamfer1)
